We just booked the Ocean Princess for November 2013 for the Tahiti cruise. When I get on the Princess site it shows a before May 2013 and a after May 2013. It doesnt seem to be on their drydock list, any ideas?

I found this story on Princess's web, is this what you were looking for?

Tahitian Princess is transformed into Ocean Princess during a two-week drydock in Singapore. From November 19 through December 2 this drydock journal will feature regular photo updates as the ship is refurbished, and the name-change process continues throughout the ship. During the busy drydock, you’ll see how much is accomplished in such a short time, and what it takes to keep Princess vessels ship-shape. We hope you enjoy this peek behind the scenes with us as we welcome Ocean Princess to the fleet!

I am not clear on what you are asking. I just went to the Princess website and did a search for Ocean Princess and got 35 cruises between now and May 2014, including every month of 2013. May 2013 shows three cruises.
